Are "optical but noIR" hosts green, perhaps Green Peas?

  • JeanTate by JeanTate

    In the center of ARG000124e: radio morphology seems to be a #bent #corejet. The host is a #faintIR source, and in SDSS it's SDSS J131512.88+415016.4, a #green STAR (i.e. a point source; in the automated SDSS photometric pipeline a lot of QSOs are STARs). NED gives two refs, both catalogs (so nothing particular about this source, or host).

    What I find particularly interesting is a possible link with the "#noIR-but-SDSS-host" objects I've found (see the Optical but #noIR host: examples here thread): most too are #green.
